Speccaton of Letters Patent.

Application filed April 18, 1905. Serial No. 256,208.

To all whom it may concern:

Beit known that I, OWEN PUTERBAUGH, a citizen of the United States, residing at Laura, in the county of Miami and State of Ohio, have invented a new and useful Pneumatic Stacker, of which the following is a specification.

This inventionvrelates to pneumatic stacking apparatus for threshing-machines, and it has particular reference to the meansv employed for effecting desired adjustment of the hood, whereby the straw passing .through the stacker-tube may be guided in the desired direction.

The invention has for its object tosimplify and improve the construction and operation of this class of devices; and with these and other ends in view, which will readily appear as the nature of the invention is better understood, thc same consists in the improved construction and novel arrangement andfcombination of parts, which lwill be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and vpreferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modi` fications to which recourse may be had with-Y in the scope of the invention and without departing from the spirit or sacrificing the efficiency of the same. v t

In said drawings, Figure 1 is a side elevation of a pneumatic stacker-tube having the invention applied thereto, the tube being shown collapsed. Fig. 2vis a similar view showingl the stacker-tube extended. Fig. 3 is a sectional detail view taken on the line 3 3 in Fig. 1. Fig. 4 is a vertical sectional de- .tail View taken through lthe upper end of the hood-adjusting device. Fig. 5 is a transverse sectionall View illustrating a modification. Fig. 6 is a longitudinal sectional detail view of the device as shown in Fig. 2.

Corresponding parts in the several {igures are indicated throughout by similar characters of reference. i

The pneumatic stacker-tube of this invention is composed in the usual manner of collapsible members 1 and 2, the latter'te'lescoping in the former. Upon the outer end of the upper member l is a hood-carrying sleeve 3, mounted for rotation, said sleeve being retained against outward displacement by means mensions, is supported for rotation, the outer bearing member 6 serving to prevent inward or downwarddisplacement of the sleeve 3, as will be readily understood. The pipe or tube 7 is provided with 'a longitudinal slot 8, and in said pipe telescopes a rod, or, if preferred,

a pipe 9, having a laterally-extending stud 10 operating in the slot 8. A bearing 11- for the lower end of the member 9 is supportedv upon the lower or inner section 2 of the stackertube, and said member 9 is provided with a crank 12 whereby it may be rotated'in its bearings, together with the tubular member 7. Itis obvious that when the member 9 is rotatedit will rotate the tube 7 by the studlO engaging the slot 8. It will be further evident that when the members 1 and 2 of the stacker-tube are extended or collapsed the members 7 and 9 will be extended or collapsed simultaneously therewith.

Upon the vupper end of the tubular member 7 is mounted a cap 13, which is closed at its outer end, as clearly seen in Fig. 4, and which is provided with anges 14 14 at the ends thereof. This cap is placed in approximate alinement with the hood-carrying sleeve and is connected with the latter by means of a cord or band l5, which may be wound one or more times upon the cap 13 and upon 4the sleeve, so that when the latter, which is rmly secured upon the tubular member 7, is rotated the hood-carrying sleeve will be likewise rotated, enabling it to be adjusted to various positions, as indicated in Figs. 1 and 2 of the drawings. The cap 13 being closed at its outer end will prevent particles of straw, chaff, and the like from working into the tubular member 7 and interfering with the operation of the device. i

Under the modification illustrated in Fig. 5 of the drawings the hood-carrying sleeve 3 is provided with anv external gear 16, meshing with a pinion 17 upon the cap 13, from which motion may thus be transmitted to the rotary hood-carrying sleeve, thev gear being simply a supbstitutefor the band means for transmitting motion.

From t e foregoing description, taken in IOO IIO

connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. When the stacker-tube is extended or collapsed, the members for operating the hood-carrying sleeve are likewise extended or collapsed, as the case may be, so that in any position of the stacker-tube the said sleeve may be rotated for the purpose of changing the position of the hood carried thereby.

Having thus described the invention, what is claimed is- A stacker-tube composed of telescoping tubular members, a hood-carrying sleeve supported for rotation upon the outer member, a longitudinally-slotted pipe supported for rotation in bearings upon said outer member, one of said bearings serving to support the hood-carrying sleeve against displacement, a member telescoping in said' pipe and having an operating-crank and a stud engaging the slot in the pipe, a cap upon the outer end oi the slotted pipe and constituting a closure for the latter, and means for transmitting motion from said cap to the rotary hood-supporting sleeve.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two Witnesses.

OWEN PUTERBAUGH.
